如何增加绑定到单个“else”的“if”条件的数量

  • 772

如何将树简化if为 10 多个以添加运行文件的允许路径？代码是这样工作的 - 文件被传输到应用程序，应用程序确定文件路径及其名称，检查路径值是否等于指定的值。

ps 所有值if应该只导致一个else表单运行

static void Main(string[] args)
{
    string filePath = args[1];
    string fileName = Path.GetFileName(filePath);
    string systemFolder = Environment.ExpandEnvironmentVariables("%SystemRoot%\\system32\\") + fileName;
    string myFolder = Environment.ExpandEnvironmentVariables("%SystemDrive%\\my\\") + fileName;
    if (filePath == systemFolder)
    {
        Process Proc = new Process();
        Proc.StartInfo.Verb = "open";
        Proc.StartInfo.FileName = fileName;
        Proc.Start();
        Application.Exit();
    }
    if (filePath == myFolder)
    {
        Process Proc = new Process();
        Proc.StartInfo.Verb = "open";
        Proc.StartInfo.FileName = fileName;
        Proc.Start();
        Application.Exit();
    }
    else
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }
}

    使用 OR 运算符 (||)

    if ((filePath == systemFolder) || (filePath == myFolder))

  2.  switch(filePath)
        {
            case myFolder:
            case systemFolder:
                {
                    Process Proc = new Process();
                    Proc.StartInfo.Verb = "open";
                    Proc.StartInfo.FileName = fileName;
                    Proc.Start();
                    Application.Exit();
                }
                break;

            default:
                {
                    Application.EnableVisualStyles();
                    Application.SetCompatibleTextRenderingDefault(false);
                    Application.Run(new Form1());
                }
                break;
        }
